摘要
FIELD: physics, acoustics.;SUBSTANCE: invention relates to encoding an audio signal. An encoding method for encoding a sample sequence in a frequency domain which is derived from an audio signal in frames, the method comprising: an interval determination step of determining an interval T between samples from a set S of candidates for the interval T, the interval T corresponding to a periodicity of the audio signal or to an integer multiple of the fundamental frequency of the audio signal; an additional information generating step of encoding the interval T determined at the interval determination step to obtain additional information; and a sample sequence encoding step of encoding a rearranged sample to obtain a code sequence.;EFFECT: high quality of encoding an audio signal with a low bit-rate with less processing.;22 cl, 10 dwg
